Muncy Twp (One of the Original Twps of the County)

I'm wanting to know where Muncy used to be in Northumberland County. I have an ancestor that lived there. I'm not from Northumberland County so I don't know anything about the original Twps which included Bald Eagle, Buffalo, Penn’s, Turbot, Augusta, Wyoming, and Muncy. Can anyone tell me where Muncy was located? Or was modern Twp it was incorporated into? Any help will be most useful.
